Abstract (en)

The basic idea of the present invention consists of taking advantage of the compatibility of almost every modem to a specific protocol called AT or Hayes commands. According to the present invention, the AT-commands will be used to generate a code specifying that the far end telecommunications device which just dialed is a modem. Therefore, when the dialed telecommunications device is connected to a PBX, latter will have to recognize said code after which it will transfer automatically that call to this telecommunications device identified by the dialed extension phone number and being a modem. Then a telecommunications connection between both modem will be set up. Advantageously, it is then possible by using present invention to connect several different telecommunications devices on a PBX, all being identified by the same extension phone number like a telephone, a FAX and a modem. A PBX according to the present invention will be able to redirect automatically a call coming from a modem to a modem. <IMAGE>
